Rubber Foam Details
Rubber Foam Factory Processing

Kingflex Rubber foam Material is soft heat-insulating, heat-preservation and energy conservation materials made with advanced technology at home and advanced full-automatic continuous production line imported from abroad, using butyronitrile rubber with best performance and polyvinyl Chloride (NBR,PVC) as main raw materials and other high quality auxiliary materials through foaming and so on special procedure.

Frequently Asked Questions (FAQ)
Q: What is the temperature range that Kingflex rubber foam can withstand?
Kingflex rubber foam insulation operates efficiently within a wide temperature range of -50°C to 110°C, as tested under standard GB/T 17794-1999 methods.
Q: What fire safety ratings does the material achieve?
The material is rated Class 0 and Class 1 according to BS 476 Part 6 & 7 testing standards. It also features a 25/50 Flame Spread and Smoke Developed Index under ASTM E 84.
Q: How effectively does Kingflex prevent water vapor transmission?
